Abstract: The invention discloses a switch short-circuit fault-tolerant control method and a system for magnetic bearing system, which belongs to the field of magnetic bearing control. N-axis magnetic bearing contains 2N H half-bridge topologies, 2N windings, and 1 DC voltage source. The current and modulation wave of each winding are monitored in real time. When a switch short-circuit fault occurs, the above data help to identify the faulty switches. By introducing the physical model of the electromagnetic force of the magnetic bearing, winding currents can be redistributed and the required electromagnetic force can be reconstructed to ensure rotor suspension and avoid serious faults such as rotor falling. This method can effectively prevent the magnetic bearing system from being destabilized when the switch short-circuit fault occurs, prevent the rotor from falling, and enable the magnetic bearing system to have the ability to operate with switch short-circuit fault tolerance.
